I got a chance to try this out yesterday at Best Buy and was pleasantly surprised at the quality of the instruments. Guitar was thick and had a nice feel, while the drums felt great with the raised cymbals. Took some hard shots and it felt very natural. Foot pedal was great with little travel and resistance.
Did a couple songs not in RB2, and I came away liking it. I'm interested in the music creation aspect, as well as playing some SOAD and Tool, but those weren't available at the store.
What are the thoughts here? I figure Rock Band will blow it away again, but it does seem to be putting up a bit of a fight.
